A bibliography of approximately 25 papers is presented on the Electron Echo Experiments. The data analysis included an extensive study of the electron accelerator beam, detector data correlations with the electron beam injections, and the study of about 30 onboard detected echoes

This is the Semi-Annual Status Report covering work performed
on grant NSG 5088 (Electron Echo IV, 21.027UE and Electron Echo V,
27.003UE) during the period 1 July, 1976 through 31 December, 1977.
Since Dr. J.R. Winckler is presently on sabbatical, we are writing
this report in his absence.
During this period, data analysis has continued on Echo IV,
which was successfully launched from Poker Flat Research Range,
Fairbanks, Alaska on 31 January, 1976. Efforts have been coordinated
with the Echo IV associate investigators from the University of
Alaska and the University of Ne\v Hampshire. The data analysis has
included an extensive study of the electron accelerator beam,
detector data correlations with the electron beam injections, and
the study of about 30 onboard detected echoes.'
Dr. J.R. Winckler, while on his sabbatical in the western
United States and Europe, has given numerous talks and exchanged
much information about the Echo IV results.
During this period Echo V development continued. The new
design of the electron gun and circuits was completed and an
increased current (200 milliamps at 40 kilovolts) gun was success-
fully tested. Also during this time a preliminary flight gun
program was designated to incorporate four of these increased
current guns. Layout and design work on the proposed payload was
also extensively pursued. In August the Echo V mission vehicle
was changed from an Aries (24.008UE) to a Nike Black Brant VC
(27.003UE). Due to thiV-change a second Echo V Pre-PIC was attended
on 21 October, 1976, with an experimenter's data package presented.

In November the feasibility and scientific merits of flying
a separated payload with experiments and telemetry on both sections
was investigated. On 17 December 1976 a new experimenter's data
package was sent to Sounding Rocket Division (3RD) with this new
separated payload design. This option of flying a separated pay-
load was later rejected in favor of a single payload due to
weight limitations of the Nike Black Brant VC.
The Echo V integration at SRD was scheduled to start the
first week in November, 1977, with the launch window at Poker
Flat Research Range set as the first week in February, 1978.
During this period there have been no publications relating
to the Echo Experiment; however, a complete Echo bibliography
is included for reference.
The Research and Technology Resume (NASA form T43) will be
completed by Professor J.R. Winckler upon his return in June.
